enum DragBridge

Swift

enum DragBridge

How a view starts an OS drag.

DropBridge's shape, facing the other way. Unset means windowed, and there is no engine fallback this time: GLFW can receive a drop but has no way to start one. So a windowed app's .onFileDrag does nothing, and the press stays an ordinary press.

Properties

nonisolated(unsafe) static var startFileDrag: Provider?

Installed by a compositor client to carry the drag to the compositor. nil, as in a windowed app, makes .onFileDrag do nothing.

Type aliases

typealias Provider = (_ paths: [String], _ chip: DragChipImage?, _ offsetX: Float, _ offsetY: Float, _ window: UInt32) -> Bool

Starts a drag of paths with chip, if any, hung offsetX,offsetY from the pointer, while the button that pressed is still held.

True when the request was delivered — not that a drag started, which is the compositor's to decide: the button may already be up, or another drag running. The last argument is the engine window the drag started in.
